To all whom it may concern:

Be it known that I, RALPH E. WILDER, a citizen of the United States, anda resident of the city of Johnstown, county of Cambriznand State ofPennsylvania, (whosepostol'lice address is Johnstown, Pennsylvania,)have invented certain new and useful in? provements in Truck-Frames; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to trucks for railway cars and particularly tothose for freight cars and to that portion known as the side frame andits appurtenances. My truck frame consists essentially of an integralmetal plate, formed with the upright portions spaced apart; the topmember being integral and the side members bent downwardly therefrom;the end members projecting longitudinally of the frame and provided withbearing surfaces adapted to rest on the tops of the journal boxes; theends of the side portions extending downwardly and inwardly inclinedfrom the tops of the journal box bearing portions; the bottom portionbeing substantially horizontal, the whole beingprovided with openingscentrally arranged, of substantially rectangular form to receive the endof the bolster: the lower portion of the oi'iening benip; provided witha spring seat, and the sides of the opening being provided with bolsterguides. The two upright web portions, which are spaced apart, aresecured together by means of a bent plate. the flanges of which areriveted near the lower portions of the side members and prefer ably alsoto the inclined portions of the side members. l also provide twotriangular openings with rounded corners in each side portion, havinginternally projectingintcgral stiffening flanges around them. Thestructural portion of my truck side frame is thus practically composedof one. sheet or plate of metal. which is formed or folded together atits upper portion, the downwardly projecting side members being spacedapart and the lower portions secured together by a. bent plate securedto both.

Having thus given of my invention I will the matter more clear,

a general description now, in order to make refer to the annexed sheetof drawings which form part of this specification and in which likecharacters refer to like parts.

F igure 1 is a side elevation of a railway car truck provided with aside frame embodying my invention; Fig. 2 is a vertical longitudinalsectional elevation; Fig. 3 is a top plan view; Fig. 4 is a verticaltransverse sectional elevation taken on the line IV J V of Fig. 3; Fig.5 is a sectional eleration taken on the line V-V of Fig. 2; and

i is an end elevation.

eferring now to the characters of reference on the drawings :1 is theside frame in general, 2 is the upper portion or top flange, 3 are thesides or webs which are sub stantially upright, spaced apart andsubstantially parallel to each other, central opening of substantiallylar outline with rounded corners, of the plate adjacent the openingvided with integral outwardly The Webs are further with triangularopenings 6 with rectanguthe edges being proextending provided roundedcorners, these being provided with inwardly formed integral with ingflanges 8. As shown, there are two side plates 3 formed integrally withthe top flange 2 and extending downwardly therefrom and substantiallyparallel to each other, and the lower portion of the truck frame and theinclined side portions are secured together by means of the bent plate14, the flanges of which adjoin and are riveled lo the webs 3 asillustrated, by means of the rivets 15. he rivets 15 are preferahlythrough rivets and are provided with sleeves or thimbles 16 between theflanges to resist the compression when driving and to further stiffenthe structure when the rivets are driven. The plate 14 is formed, asshown. with llang'es'by doubling or folding the plate. and theintermediate part of the outwardly extending portions 22 rests upon theupper surfaces of theflanges 5 and assister I!) forming the spring seatas illustrated. The portions 22 are of slightly less length than that ofthe bolster opening as shown. The spring plank 17, which is of channelform. is secured, as illustrated, and riveted through the flanges 5 andthe extending portions 22 as shown. Column guides 18 are secured to theflanges 5, these column guides being formed of pressed plates,illustinted. The bolster is 12!, the springs 30) the brake hangercarriers are 21 the entire extending portions of the bent plate are 22,and journal boxes .23 of the us- ,ype are used. Bearing plates 10 aresewn-ed. to the laterally projecting emls of the frame to form seats tobear upon the tops of the journal boxes. Holes ll provided in thejournal bearing plate 1!), and. other openings 12 are provided near liteends of the upper flange member through which the journal box bolts 9may be pa for securing the journal boxes to the t frame. The usualpedestal tie 3 shown as riveted to the triuzk from; cured to the lowerportions of the boxes by means of the journal bro; 1

Although I have described and il my invention in considerable detail, 5not wish to be limited to the exact liIlLi sage eific details thereof asshown and described, but may use such modifications in, substitutionsfor, or equivalents thereof, as are embraced within the scope of myinvention or as pointed out in the claims Having thus described myinvention, what I claim and desire to secure in; lie-l Hers Patent. is
